Embodiment
Hereinafter, explain the SOFC unit module of present embodiment and use this solid
The SOFC of oxide body type fuel battery cell module.In addition, illustrate for convenient, the chi of accompanying drawing
Very little ratio has been exaggerated, and there is a situation where different from the ratio of reality.
[first embodiment]
As shown in figure 1, the unit module 10 of present embodiment possesses the cell substrate 1 with gas permeability.Moreover, unit mould
Block 10 possesses：Any one electrode 2 in fuel electrodes and air pole, it is formed on cell substrate 1；Solid electrolyte 3, it is formed
In on an electrode 2；Another electrode 4, it is formed on solid electrolyte 3.
Moreover, as shown in Fig. 2 in the SOFC 20 of present embodiment, unit module 10 is by firing
Expect pole connectors 21 (fuel electrodes barrier film) and air pole connectors 22 (air pole barrier film) clamping.Fuel electrodes connectors 21 possess more
Individual fuel gas channel 21a, air pole connectors 22 possess multiple oxidant gas stream 22a.Also, fuel gas channel
21a and oxidant gas stream 22a turns into many linear streams (parallel stream) configured concurrently with each other.
Located at the stream of fuel electrodes connectors 21 and air pole connectors 22 (fuel gas channel 21a, oxidant gas stream
Road 22a) cross sectional shape be made up of the convex portion that is referred to as rib and the recess for being referred to as passage.Wherein, fuel electrodes connectors are passed through
21 and the ribs of one of air pole connectors 22 contacted with cell substrate 1, electronics is led between connectors and cell substrate 1
It is logical.In addition, being contacted by the rib of the other of fuel electrodes connectors 21 and air pole connectors 22 with another electrode 4, make
Electronics turns between connectors and another electrode 4.
Here, the fuel gas flowed in fuel gas channel 21a and the oxygen flowed in oxidant gas stream 22a
Oxidant gas can also be the relative stream (convection current) relatively flowed in the face of unit module 10.In addition, fuel gas and oxygen
Oxidant gas can also be the parallel stream (co-flow) flowed in the face of unit module 10 along identical direction.
In addition, it is following, illustrate for convenient, an electrode 2 is set to fuel electrodes, another electrode 4 is set to air pole
To be illustrated to the unit module 10 of present embodiment.In this case, turn into fuel electrodes connectors 21 to connect with cell substrate 1
Touch, the structure that air pole connectors 22 contact with air pole.
It is along identical side in the face of unit module 10 in fuel gas and oxidant gas as shown in Fig. 1 (a)
To flowing parallel stream in the case of, the unit mould at the export department 1c of fuel gas and oxidant gas as shown in Figure 3
Deblocking temperature highest.That is, in the case of parallel flow pattern, heating and the heat as caused by Joule heat as caused by cell reaction
Downstream side is transmitted under the effect for the convective heat transfer brought by working fluid.Therefore, the temperature of unit module is with from gas
The entrance of body stream reaches outlet and risen.
Such phenomenon is either in the case where the porosity of cell substrate 1 is constant in entire surface or such as patent
Document 1 is all identical in the case of improving the porosity at the export department of fuel gas and oxidant gas like that.The phenomenon without
By being that experimentally or in the literature will be apparent from, various reports be present since conventional.Such as in K.Lai,
B.J.Koeppel, K.S.Choi, etal., " Aquasi-two-dimensional electrochemistry modeling
Tool for planar solid oxide fuel cell stacks, " Journal of Power Sources,
The comparison of the experimental result and analog result of Temperature Distribution is recorded in vol.196, no.6, pp.3204-3222,2011..Especially
It is, if the porosity in gas downstream side lift unit substrate, i.e. fuel gas easily enters fuel as described in Patent Document 1
The power generating surface portion of pole 2, then generated energy increase of the generated energy at the export department 1c of fuel gas than inlet portion 1a.Therefore, with
The situation that the porosity of cell substrate 1 is constant is compared, and the temperature of the unit module at export department 1c is easy to intensively rise.
On the other hand, it is the phase in the face of unit module 10 in fuel gas and oxidant gas as shown in Fig. 1 (b)
In the case of the relative stream flowed over the ground, the Temperature Distribution different from the situation of parallel stream is presented.Specifically, in relative stream
In the case of, be not oxidant gas in unit module 10 and fuel gas inlet portion 1a and export department 1c, but in
The part that 1b generation unit module temperatures in centre portion uprise.The reason is that in the case of relative stream, the outlet of oxidant gas
Side turns into the entrance side of fuel gas, and the fuel gas of low temperature flows into the outlet side of oxidant gas.Therefore, with the export department
1c compares with inlet portion 1a, and central portion 1b unit module temperature is easier to intensively rise.
In this way, in the case where fuel gas and oxidant gas are the either case of parallel stream and relative stream, unit module 10
Temperature all partly rises, it is possible to more than working limit temperature, causes the reduction of durability.Therefore, in order to suppress local
Temperature rises, in the present embodiment, make the part corresponding with high-temperature portion in unit module 10 cell substrate 1 it is ventilative
Rate reduces.That is, in the case of parallel stream, set the export department 1c of the fuel gas in cell substrate 1 air penetrability
Surely must be lower than the air penetrability of the part in addition to export department 1c in cell substrate 1.Thus, in export department 1c, fuel gas
Arrival to the surface of fuel electrodes 2 is suppressed, therefore, the lower power production of the downstream portion (export department 1c) of individual unit.
In this case, in order to which individual unit obtains identical output, insufficient generated energy supplies in upstream side, therefore upstream portion (entrance
Portion 1a) generated energy increase.As a result, temperature rises at the inlet portion 1a of low temperature, temperature reduces at export department 1c, because
This, export department 1c high temperature, which is concentrated, to be alleviated, and can make the overall equalizing temperature of unit module.
It is described in more detail, as shown in Fig. 4 (a), in patent document 1, stomata is lifted in the downstream of gas flow path
Rate, improve air penetrability.But, in the present embodiment, air penetrability is set in the downstream of gas flow path relatively low.Cause
This, as shown in Fig. 4 (b) and Fig. 5, compared with the structure of patent document 1, the temperature drop at the export department 1c of unit module 10
It is low, therefore, it is possible to be maintained at less than the state of working limit temperature.As a result, the heat ageing of unit module 10 can be suppressed, make resistance to
Long property improves.
As described above, in the case of relative stream, as shown in Fig. 6 (a), by the unit base in gas flow direction
The central portion 1b of plate 1 air penetrability is set to the ventilative of the inlet portion 1a and export department 1c than the fuel gas in cell substrate 1
Rate is low.Thus, in central portion 1b, arrival of the fuel gas to the surface of fuel electrodes 2 is suppressed, therefore, individual unit
Generated energy at central portion 1b is suppressed.In this case, in order to obtain identical output, insufficient generated energy exists individual unit
Inlet portion 1a and export department 1c supplies in addition to central portion 1b, the generated energy increase of the part in addition to central portion 1b.
As a result, as shown in Fig. 6 (b), temperature rises at the part in addition to central portion 1b, and temperature drops at central portion 1b
Low, therefore, central portion 1b high temperature, which is concentrated, to be alleviated, and can make the overall equalizing temperature of individual unit.
In FIG. 7, it is shown that in the higher part of the temperature of unit module, the air penetrability of cell substrate and maximum temperature it
Between relation.Specifically, in the case of parallel stream, the export department 1c's of the fuel gas in expression cell substrate 1 is ventilative
Relation between rate and maximum temperature.In addition, in the case of relative stream, cell substrate 1 in gas flow direction is represented
Relation between central portion 1b air penetrability and maximum temperature.In the figure 7, air penetrability be 1.0 expressions be with cell substrate its
His place identical air penetrability.In addition, air penetrability be 0.6 expression 6 into gas permeation, that is to say, that the transit dose of gas is reduced
4 into.
As shown in fig. 7, in the case where reducing air penetrability, the tendency of the maximum temperature reduction of display unit module,
In the case of reduce further air penetrability, tendency that the maximum temperature of display unit module rises on the contrary.Therefore, unit module
Maximum temperature turn into minimum air penetrability be 0.6 or so.Thus, considering manufacturing condition, the unit module of cell substrate
Temperature decreasing effect in the case of, preferably air penetrability is set to 0.4~0.8, is more preferably set to 0.5~0.7.In other words, in list
In first substrate 1, the air penetrability lower than the air penetrability of other parts 40%~80% of the preferably relatively low part of air penetrability is more preferably low
30%~50%.
As long as in addition, it can obtain between the air penetrability at the relatively low part of air penetrability and the air penetrability of other parts
Relative value, the assay method of the air penetrability of cell substrate 1 are just not particularly limited.The air penetrability of cell substrate 1 being capable of use example
Determined such as differential air penetrability evaluating apparatus.
Then, to carrying out the method that the air penetrability of cell substrate 1 changes for the flow locations using reacting gas
Explanation.In addition, illustrate for convenient, in the case of suitable for relative stream, make air penetrability at the central portion 1b of cell substrate 1
The method of reduction illustrates.In addition, it also can similarly carry out in the case of being applied to parallel stream, make going out for cell substrate 1
The method that oral area 1c air penetrability reduces.
In the present embodiment, by setting cell substrate 1 can be made to compress the compact part formed to make cell substrate 1
Air penetrability reduces.That is, the compact part is to be directed to the cell substrate 1 with uniform air penetrability to be intended to reduce air penetrability
Partial shrinkage and be recessed, make air penetrability produce change to form.
Specifically, as shown in Fig. 8 (a) and (b), for the cell substrate 1 with uniform air penetrability, by that will think
The part that air penetrability reduces is recessed from the compression of the lower surface of cell substrate 1, form compact part 1d.Also, such as Fig. 8 (c)
It is shown, by being laminated fuel electrodes 2, solid electrolytic on the even surface (upper surface) of the opposite side of the lower surface in cell substrate 1
Matter 3 and air pole 4, obtaining unit module 10.In addition, the laminating method of fuel electrodes 2, solid electrolyte 3 and air pole 4 does not have
It is particularly limited to, known method can be used.
The density raising by compression of cell substrate 1, therefore fuel gas is difficult to enter such compact part 1d.Therefore, exist
Compact part 1d, the transmitance of fuel gas are reduced, and the fuel gas entered to fuel electrodes 2 is reduced.Thus, with implementing so
The generated energy of the relative individual unit of compact part of compression process reduce, therefore, it is possible to drop the maximum temperature of unit module
It is low.In addition, by the decrement to compact part 1d, that is the thickness of compact part, density are adjusted, can easily obtain
Obtain desired air penetrability.
In addition, compact part 1d can also be formed at the entirety for the part that air penetrability to be made reduces.That is, in relative stream
In the case of, compact part 1d can also be integrally formed in the central portion 1b of cell substrate 1.In addition, in the case of parallel stream,
Compact part 1d can also be integrally formed in the export department 1c of cell substrate 1.But, compact part 1d is by from cell substrate 1
Lower surface compression and be recessed what is formed, the rib of the part of depression not with fuel electrodes connectors 21 contacts, and existing can not be fully
Ensure the possibility of the conducting between cell substrate 1 and fuel electrodes connectors 21.
Therefore, in the present embodiment, as shown in Fig. 8 (c), (d), (e), it is preferred that by compact part 1d along combustion
The circulating direction (Z-direction) of material gas is formed as lengthwise shape, further by multiple compact part 1d in the side vertical with Z-direction
Set at spaced intervals on to (X-direction).By so setting multiple compact part 1d at spaced intervals, in air penetrability to be made
In the part of reduction, also electrically connected between cell substrate 1 and fuel electrodes connectors 21.It is accordingly possible to ensure cell substrate 1 and combustion
Expect the conducting between pole connectors 21.In addition, by the way that multiple compact part 1d are set at spaced intervals, further by densification
Portion 1d width, interval and density is adjusted, and can obtain desired air penetrability.
In the present embodiment, as cell substrate 1, as long as there is gas permeability and with as the sufficient strong of supporting mass
Degree, is just not particularly limited, preferably using the higher cell substrate of electrical conductivity.It can be applicable by containing such as nickel (Ni), chromium
(Cr) corrosion resisting alloy, corrosion resisting steel, stainless steel etc. form and possess the substrate of perhaps lacunose tabular.Specifically, energy
It is enough to use formed by above-mentioned material, punch metal substrate, etching metal substrate, metal lath substrate, foaming metal body, metal
The metallic mesh such as sintered powder, woven wire, metal non-woven fabrics etc..In addition, these can also be laminated as needed it is of the same race
Or the substrate of xenogenesis.
As fuel electrodes 2, can rightly using reducing atmosphere it is relatively strong, pass through fuel gas, electrical conductivity is high, have will
Hydrogen molecule is converted into the fuel electrodes of the catalyst action of proton.As the constituent material of fuel electrodes, there is also separately from for example
The situation of the metals such as nickel (Ni), but being preferably applicable mixes the oxygen ion conduction body representated by yttria stabilized zirconia (YSZ)
The cermet formed together.By using such material, to increase conversion zone, electrode performance can be improved.This
Outside, yttria stabilized zirconia (YSZ) is substituted, samarium doping cerium oxide (SDC) can be also applicable, adulterate the cerium oxide of gadolinium oxide
(GDC) cerium solid solution as.
As air pole 4, can rightly using oxidizing atmosphere it is relatively strong, pass through oxidant gas, electrical conductivity is higher, tool
There is the air pole for the catalyst action that oxygen molecule is converted into oxide ion.In addition, air pole 4 both can be by electrode catalyst
Form, can also be made up of the cermet of electrode catalyst and electrolyte.As electrode catalyst, there is also Application Example
